Single Hose Adapter MK2 for Divesoft BOV. The Adapter allows you to reduce the number of hoses routed to your BOV from 2 to only one hose. This results in your BOV's 2nd stage regulator and MAV being fed by a single hose from your unit's 1st stage regulator improving your head movement. The MK2 has a significantly improved flow rate when switched to Open Circuit.

NOTE:

When installed to your BOV, DO NOT use a wrench to tighten it. Finger-tight is enough in this case. SHA does not screw all the way in on the lower (2nd stage) thread. A few screw threads will be always visible. Overtightening will cause the BOV and MAV to warp which leads to water/gas leaks and damage to the unit itself.
